Multiclavula vernalis  

Fruit-bodies simple, to 20 mm high, clavate; colour creamy to fleshy cream or straw-orange when fresh, dull ochraceous orange when dry, then usually with a small white spot at the apex like a cap, soft and flexible, terrestrial, ephemeral. Hymenium extending over approximately the upper two thirds of the fruit-body. Basidia 7-20 x 4-7 μm, bearing a basal clamp connection, 4-sterigmate. Sterigmata to 7 μm long, spindly, slightly incurved. Tortuous sterile hyphal tips protrude from the young hymenium and among the basidia. Basidiospores 8-12 x 2.5-3.5 μm, ellipsoidal to elongate-ovoid, smooth, thin-walled, aguttulate, white in prints, bearing a small indistinct eccentric apiculus. Contextual hyphae somewhat parallel, loosely arranged toward the apex of the fruiting body, not agglutinated, short-celled (10-90 x 2-5 μm), thin- to slightly thick-walled; branching and anastomoses abundant. Subhymenial hyphae thin-walled, parallel to the contextual hyphae, bearing clamp connections throughout, producing basidia as side branches.
